Description
Die Erfindung betrifft eine Ölförderpumpe mit einem Pumpengehäuse, einem im Pumpengehäuse drehbar gelagerten Rotor, einem im Rotor verschieblich gelagerten Flügel, dessen Flügelspitzen an der Innenumfangswand eines Pumpenraums anliegen und diesen in einen Saugraum und einen Druckraum unterteilen, wobei sich der Flügel quer zur Drehachse des Rotors erstreckt, und mit einem in den Saugraum mündenden Einlass und einem vom Druckraum ausmündenden Auslass, wobei der Einlass und der Auslass in der Innenumfangswand des Pumpenraums angeordnet sind und das Pumpengehäuse zwei Pumpenräume aufweist und jeder Pumpenraum mit einem Gehäusedeckel verschließbar ist.The invention relates to an oil feed pump having a pump housing, a rotor rotatably mounted in the pump housing, a rotor slidably mounted in the rotor whose vane tips bear against the inner peripheral wall of a pump chamber and divide it into a suction chamber and a pressure chamber, wherein the wing transverse to the axis of rotation of the rotor extends, and with an opening into the suction inlet and an outlet opening from the pressure chamber, wherein the inlet and the outlet are arranged in the inner peripheral wall of the pump chamber and the pump housing has two pump chambers and each pump chamber is closable with a housing cover.
Es sind Vakuumpumpen bekannt (
Der Erfindung liegt die Aufgabe zugrunde, eine Ölförderpumpe bereitzustellen, mit weicher nicht nur Gase, sondern auch Flüssigkeiten gefördert werden können, wobei die Pumpe einerseits einen kleinen Bauraum aufweist, andererseits ein hohes Ölfördervolumen besitzt, einfach aufgebaut ist und zudem eine geringe Verlustleistung aufweist und die dennoch einen hohen Wirkungsgrad aufweist, auch bei höheren Fertigungstoleranzen.The invention has for its object to provide an oil pump with softer not only gases, but also liquids can be promoted, the pump on the one hand has a small space, on the other hand has a high oil flow, is simple and also has a low power loss and the still has a high efficiency, even at higher manufacturing tolerances.
Diese Aufgabe wird erfindungsgemäß mit einer Ölförderpumpe der eingangs genannten Art gelöst, bei der der Rotor von zwei, insbesondere axial hintereinander angeordneten Rotorabschnitten gebildet wird, wobei jeder Rotorabschnitt in einen der beiden Pumpenräume eingesetzt ist. Außerdem ist ein Rotorabschnitt mit einem zapfenförmigen axialen Ende und der andere Rotorabschnitt mit einem axialen hülsenförmigen Ende versehen, wobei das eine Zapfenende in das andere Hülsenende eingesteckt ist.This object is achieved with an oil feed pump of the type mentioned, in which the rotor of two, in particular axially successively arranged rotor sections is formed, each rotor section is inserted into one of the two pump chambers. In addition, a rotor portion is provided with a peg-shaped axial end and the other rotor portion with an axial sleeve-shaped end, wherein the one end of the spigot is inserted into the other end of the sleeve.
Bei der erfindungsgemäßen Ausgestaltung der Ölförderpumpe liegen der Einlass und der Auslass in radialer Richtung, was den wesentlichen Vorteil hat, dass das Öl nur geringe Umlenkungen erfährt, also nicht von einer axialen Anströmrichtung in eine radiale Richtung oder Umfangsrichtung umgelenkt werden muss, sondern radial in den Pumpenraum einströmt und aus diesem wieder radial ausströmt. Bei Pumpen, mit welchen Gase gefördert werden, spielt dieser Aspekt eine untergeordnete Rolle, da Gase eine relativ geringe Masse aufweisen. Bei Flüssigkeiten ist dieser Aspekt nicht mehr vernachlässigbar, sondern spielt eine entscheidende Rolle, da axial anströmende Flüssigkeiten vom Flügel beschleunigt werden müssen, was zusätzliche Energie erfordert.In the inventive design of the oil feed pump, the inlet and the outlet are in the radial direction, which has the significant advantage that the oil undergoes only small deflections, so does not have to be deflected by an axial direction of flow in a radial direction or circumferential direction, but radially into the Pump chamber flows in and out of this flows radially again. In pumps with which gases are conveyed, this aspect plays a minor role, since gases have a relatively low mass. For liquids, this aspect is no longer negligible, but plays a crucial role, since axially inflowing liquids must be accelerated by the wing, which requires additional energy.
Die erfindungsgemäße Ausgestaltung besitzt den Vorteil, dass lediglich ein einziger Antrieb erforderlich ist, und mit diesem Antrieb beide Rotorabschnitte angetrieben werden. Eine derartige Ölförderpumpe ist leicht regelbar und besitzt ein hohes Fördervolumen. Dabei können die Pumpenräume gleich oder unterschiedliche Volumen aufweisen. Hierdurch wird nicht nur eine einfache Lagerung geschaffen, sondern es werden auch axiale Toleranzen ausgeglichen, insbesondere axiale Lagetoleranzen der beiden Pumpenräume bezüglich der beiden Rotorabschnitte.The embodiment of the invention has the advantage that only a single drive is required, and driven with this drive both rotor sections. Such an oil pump is easy to control and has a high flow rate. The pump chambers may have the same or different volumes. As a result, not only a simple storage is created, but also axial tolerances are compensated, in particular axial position tolerances of the two pump chambers with respect to the two rotor sections.
Erfindungsgemäß weist der Flügel eine konstante Länge auf. Dies hat den Vorteil, dass der Flügel zum einen einfach herstellbar ist, zum anderen die Montage einfach erfolgen kann, da der Flügel nicht aus mehreren Bauteilen, zum Beispiel Flügelkörper mit Flügelspitzen und gegebenenfalls dazwischen angeordneten Federmitteln, aufgebaut ist. Der Flügel kann selbstverständlich in Form einer Fachwerkstruktur mit in Längsrichtung des Flügels und/oder parallel zur Drehachse verlaufenden Kanälen oder Einsenkungen versehen sein. Hierdurch wird Gewicht eingespart, wodurch die Trägheitskräfte verringert können und der Flügel mit geringerem Kraftaufwand beschleunigt und verzögert werden kann. Auf diese Weise wird die Abnutzung der Flügelspitzen verringert.According to the invention, the wing has a constant length. This has the advantage that the wing is on the one hand easy to manufacture, on the other hand, the assembly can be done easily because the wing is not made up of several components, for example, wing body with wing tips and optionally arranged therebetween spring means. The wing can of course be provided in the form of a truss structure with extending in the longitudinal direction of the wing and / or parallel to the axis of rotation channels or depressions. As a result, weight is saved, whereby the inertial forces can be reduced and the wing can be accelerated and decelerated with less effort. In this way, the wear of the wing tips is reduced.
Bei einer Ausführungsform liegen der Einlass und der Auslass in der gleichen Querschnittsebene. Eine andere, alternative Ausführungsform sieht vor, dass der Einlass und der Auslass axial versetzt zueinander angeordnet sind. Hierdurch kann unterschiedlichen Anschlussarten für zuführende und abführende Leitungen Rechnung getragen werden, da diese Leitungen an der Außenseite des Pumpengehäuses angeordnet werden müssen.In one embodiment, the inlet and the outlet are in the same cross-sectional plane. Another alternative embodiment provides that the inlet and the outlet are arranged axially offset from one another. As a result, different types of connection for feeding and discharging lines are taken into account, since these lines must be arranged on the outside of the pump housing.
Mit Vorzug weisen der Einlass und der Auslass in radialer Richtung verlaufende Wandflächen auf. Dies bedeutet, dass der Einlass und der Auslass sich innerhalb der Wand des Pumpengehäuses in radialer Richtung nach außen aufweiten. Auf diese Weise werden Strömungsverluste verringert.With preference, the inlet and the outlet in the radial direction extending wall surfaces. This means that the inlet and the outlet expand radially outward within the wall of the pump housing. In this way flow losses are reduced.
Bei einer Weiterbildung wird im einen Pumpenraum Öl oder Öl-Gas-Gemisch und im anderen Pumpenraum ein Gas gefördert, insbesondere abgesaugt. In a further development, in one pump chamber oil or oil-gas mixture and in the other pump chamber a gas is conveyed, in particular extracted.
Eine einfache Lagerung wird dadurch geschaffen, dass das Hülsenende des einen Rotorabschnitts im Pumpengehäuse, insbesondere in der Trennwand zwischen den beiden Pumpenräumen, gelagert ist. Dabei bildet auch das Hülsenende des einen Rotorabschnitts das Lager für das Zapfenende des anderen Rotorabschnitts. Eine Schmierung dieser Lager erfolgt vorteilhafterweise über das zumindest von einem der beiden Pumpenräume geförderte Schmieröl.A simple storage is created by the fact that the sleeve end of a rotor section in the pump housing, in particular in the partition wall between the two pump chambers, is stored. In this case, the sleeve end of a rotor section forms the bearing for the journal end of the other rotor section. Lubrication of these bearings is advantageously carried out via the at least one of the two pump chambers promoted lubricating oil.
Eine einfache Drehkopplung der beiden Rotorabschnitte erfolgt erfindungsgemäß dadurch, dass die beiden Enden der Rotorabschnitte über ein Vielkeilprofil, eine Nut-Feder-Verbindung oder ein Polygonprofil miteinander verbunden sind. Hierdurch wird gewährleistet, dass die beiden Rotorabschnitte in Drehrichtung miteinander gekoppelt sind, in axialer Richtung jedoch gegeneinander verschoben werden können. Hierdurch können herstellungsbedingtes Spiel, temperaturbedingte Längenänderungen des Rotors und des Pumpengehäuses und dergleichen ausgeglichen werden.A simple rotational coupling of the two rotor sections takes place according to the invention in that the two ends of the rotor sections are connected to one another via a splined profile, a tongue and groove connection or a polygonal profile. This ensures that the two rotor sections are coupled together in the direction of rotation, but in the axial direction can be moved against each other. As a result, manufacturing-related game, temperature-induced changes in length of the rotor and the pump housing and the like can be compensated.
Die beiden Pumpengehäuse können seriell oder parallel geschaltet werden. Hierdurch kann die Pumpe hinsichtlich des Fördervolumens und des Saugdrucks den geforderten Bedingungen angepasst werden. Insbesondere ist bei einer seriellen Schaltung der nachfolgende Pumpenraum größer als der vorhergehende Pumpenraum.The two pump housings can be connected in series or in parallel. As a result, the pump can be adapted to the required conditions with regard to the delivery volume and the suction pressure. In particular, in a serial circuit of the subsequent pump chamber is larger than the previous pump room.
Vorzugsweise sind die beiden Pumpenräume im Pumpengehäuse axial hintereinander angeordnet und werden gleichzeitig vom Rotor axial durchsetzt. Diese Ausgestaltung bietet den wesentlichen Vorteil, dass die Pumpen die oben genannten Eigenschaften besitzt und dass sie zudem schnell und einfach montierbar ist, was insbesondere maschinell erfolgen kann.Preferably, the two pump chambers are arranged axially behind one another in the pump housing and are simultaneously penetrated axially by the rotor. This embodiment has the significant advantage that the pump has the above properties and that it is also quick and easy to install, which can be done in particular by machine.
Vorteilhaft liegt zwischen den beiden Pumpenräumen eine Gehäusewand, in welcher zumindest einer der Rotorabschnitte gelagert ist. Diese Gehäusewand bildet den Boden für beide Pumpenräume, wobei jeder Pumpenraum von einem eigenen, separaten Deckel verschlossen wird.Advantageously, between the two pump chambers is a housing wall in which at least one of the rotor sections is mounted. This housing wall forms the bottom for both pump chambers, each pump chamber is closed by its own, separate cover.
Mit Vorzug sind die Rotorabschnitte in Drehrichtung um 90° versetzt in die Rotorräume eingesetzt. Hierdurch wird das Pumpgeräusch der Ölpumpe beträchtlich verringert und das Pulsieren der Ölpumpe wird auf ein Minimum herabgesetzt. Außerdem ist die Leistungsaufnahme der Pumpe wesentlich gleichmäßiger.With preference, the rotor sections are inserted in the direction of rotation offset by 90 ° in the rotor chambers. As a result, the pumping noise of the oil pump is considerably reduced and the pulsation of the oil pump is reduced to a minimum. In addition, the power consumption of the pump is much more uniform.
Mit Vorzug sind der Einlass und der Auslass der Ölpumpe ventilfrei, so dass hierdurch ebenfalls Leistungsverluste verringert werden.With preference, the inlet and the outlet of the oil pump are valve-free, so that this also reduces power losses.
